Mattio,
Not sure if it helps, but you could consider permanently boosting the
quality of biographies, via xdmp:set-document-quality() or a related
function.
If I understand what you're trying to do correctly, you could also make
your query test for a matrix of possibilities at runtime. You didn't say
what the element name is for your type attribute, but let's say it's
'document'.
let $user-query := 'baseball'
let $query := cts:or-query((
let $booster := cts:element-attribute-value-query(
xs:QName('document'), xs:QName('type'), 'biography'
)
for $i in (
$user-query,
cts:element-word-query(xs:QName('title'), $user-query, (), 16)
)
return (
$i,
cts:and-query(($booster, $i))
)
))
return $query
=>
cts:or-query((
cts:word-query("baseball", ("lang=en"), 1),
cts:and-query((
cts:element-attribute-value-query(
xs:QName("document"), xs:QName("type"), "biography",
("lang=en"), 1
),
cts:word-query("baseball", ("lang=en"), 1)
), ()),
cts:element-word-query(
xs:QName("title"), "baseball", ("lang=en"), 16),
cts:and-query((
cts:element-attribute-value-query(
xs:QName("document"), xs:QName("type"), "biography",
("lang=en"), 1
),
cts:element-word-query(
xs:QName("title"), "baseball", ("lang=en"), 16)
), ())
))
You can probably see why I wrote a query to generate that query :-).
Note that I didn't actually boost the score for the biography matches:
they'll be boosted by TF/IDF naturally, as will the title matches
(assuming title matches are less frequent, in TF/IDF terms, than
word-query matches are). Very often, there isn't much reason to
explicitly boost query terms.
You might also think about creating a field for this query, if it's a
frequently-used search strategy for your application.

I have a query that searches for a term. If the term occurs in a
title or head element, the score is boosted.
cts:or-query((
cts:word-query("baseball", (), 1),
cts:element-word-query(
(xs:QName("title"), xs:QName("head")), "baseball", (), 16
)
))
If I have two documents where one has an attribute type="biography",
can I form the query to return *both* documents but boost the score up
further on the "biography" one?
This has been stewing for a few days now and I've been trying
different versions in cq, but I can't see how to put the cts:query
constructors together to do it.
Thanks for any help,
Matt
